Got a partial tick at around 21:30 - Faction status summary got updated, but not the system and system map.
It's now 22:30 and the system map isn't updated yet, still the wrong INF for the faction I'm monitoring.
Now at 11:30 the system map shows the correct results. Don't know when the change happened.
The time difference between calculating the INF and then showing the results in the system map and in-game (a station changed faction) was big. Hopefully FDev fixes this with 3.3 or with the next server maintenance.
